UNITED STATES PATENT OFFICE.

RICHARD N. ALLEN, OF CLEVELAND, OHIO.

ELECTRO-MAGNETIC LOCOMOTIVE.

SPECIFICATION forming part of Letters Patent No. 429,107, dated June 3, 1890.

I Application filed January 24, 1890. Serial No. 337,976. (No model.)

Be it known that I, RICHARD N. ALLEN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Electro-Magnetic Locomotives, of which the following is a specification, reference being had to the drawings accompanying and forming a part of the same.

This invention in an improvement in the application of electromagnetic motors to the propulsion of cars or other vehicles; and it consists in a novel form of what may be termed an electric locomotive.

In other words, the invention has in view the construction of a car driven by an electric motor and adapted to draw or propel other cars rather than to serve itself as a conveyance for passengers.

The aim of the invention is, primarily, to provide a practical and efficient means for imparting the motion of the motor to the driving-wheels and for protecting the motor from the effects of dust and exposure to the weather.

In carrying out my invention I mount the motor on supports secured to the truck or a frame in which the axles are journaled and at a certain height above said frame or truck I also mount on the truck a counter-shaft driven by the motor through reducing spungears and connected directly to the drivingwheels by crank-pins and connecting-rods or by gear-wheels.

In this combination my invention resides, and the special advantages and desirability of the same will appear from the more detailed description which follows.

Figure 1 is a side elevation of my improved engine or car. Fig. 2 is a top plan View of the same, the supports of the car being removed. Fig. 3 is a side elevation of the same, showing a modification of the construction for transmitting motion to the driving-wheels; and Fig. 4 is a plan view of the same.

A designates the bottom of a car or the supports upon which it rests, and B the frame or truck upon which said car is mounted, with intermediate springs or cushions C.

D D are the driving-wheels, the axles of which are journaled in the frame or truck B in proper bearings.

E are vertical supports secured to the frame B, and forming, with the cross-bars E, a strong frame-work above the truck for the motor F, which is mounted thereon in any proper manner, as by projections G, from its field-magnets, that are bolted to the cross-bars E. The wheels and the motor, being thus carried by a rigid frame, are preserved in fixed relation and may be connected by a system of gears. The means which I employ for this purpose are as follows:

H is a pinion on the end of the motor-shaft. This meshes with a spur-wheel I, carried by a counter-shaft J, having bearings in arms K, secured to the motor-frame or the field-magnets of the'motor.

Apinion L at the opposite end of the shaft J meshes with a spur-wheel M on a shaft N,

which is mounted in bearings on the truck 13- and in line with the two axles of the drivers D D To the ends of the shaft N are preferably secured crank-wheels o 0, with wrists or pins connected by connecting-rods to cranks P on the axles of the driving-wheels. It is desirable to employ a rigid pitman R to connect the pins S with one set of drivers, and a pitman T, pivoted to R, to impart motion to the other drivers. By this construction any displacement of the motor and driving-wheels is prevented. The motor may be run at a high speed, which is desirable, and being raised up above the truck it may be readily covered and protected from dust and moisture.

Instead of employing the crank-wheels o 0 and connecting-rods 'R T as means for transmitting motion from shaft N to the drivingwheels the construction shown in Figs. 3 and 4: of the drawings may be substituted.

In the figures, U U represent gear-wheels secured to the ends of the axles of the driving-wheels D and D, the axles being extended to project sufficiently beyond or outside of the driving-wheels for this purpose.

V is a gear-wheel secured to the end of shaft N, this shaft being extended sufficiently to bring the wheel V into the same vertical plane with the wheels U U, and these three wheels being constructed and arranged to mesh with each other. In this arrange ment it is desirable to set the driving-wheels somewhat nearer each other than in the ar= rangement shown in Figs. 1 and 2, so that the wheels U U can mesh with the wheel Vwithout bringing their peripheries too near the track. These gear-wheels, although shown in'the drawings upon only one side of the truck, are prpferably applied to both sides. By this construction and arrangement the driving-Wheels upon each side of the car are connected directly with the shaft N, as well as by the use of crank-wheels and connecting-rods, as shown in Figs. 1 and 2.

The invent-ion is not limited to the employment of any special form of motor nor kind of gearing, except that the essential feature of the invention involves the rotary shaft N, from which motion is transmitted directly by cranks and connecting-rods or by gears to the driving-wheels.

hat I claim as my invention is 1. The combinatiomwith the truck or frame, of the driving-wheels having bearings therein, the uprights or frame rigidly secured to the truck, the motor mounted on said frame, a shaft mounted on the truck,intermediate reducing-gears between the motor and said shaft,

and connections between said shaft and the driving-wheels, as herein set forth.

2. The combination,with the truck or frame, of the driving-wheels having bearings therein, the uprights or frame rigidly secured to the truck, the motor mounted on said frame, a shaft mounted on the truck, intermediate reducing-gears between the motor and said shaft, and crank-connections between said shaft and the driving-wheels, as herein set forth.

lhe combination, with a truck and a car supported on springs or cushions by said truck, of driving-wheels and axles jonrnaled in the truck, a motor supported rigidly above the truck, a counter-shaft mounted on the truck, intermediate gears between the motor and shaft, crank-wheels carried by the shaft, and connecting-rods from the same to the driving-wheels, as set forth.

RICHARD N. ALLEN.
